Abstract

Mg16BeAl12 crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are five inequivalent Mg sites. In the first Mg site, Mg is bonded in a 12-coordinate geometry to six Mg, one Be, and five Al atoms. There are a spread of Mg–Mg bond distances ranging from 3.04–3.34 Å. The Mg–Be bond length is 3.06 Å. There are a spread of Mg–Al bond distances ranging from 2.94–3.11 Å. In the second Mg site, Mg is bonded in a 12-coordinate geometry to seven Mg and five Al atoms. There are one shorter (3.00 Å) and four longer (3.10 Å) Mg–Mg bond lengths. There are a spread of Mg–Al bond distances ranging from 2.99–3.12 Å. In the third Mg site, Mg is bonded in a 10-coordinate geometry to four Mg and six Al atoms. There are two shorter (3.03 Å) and one longer (3.12 Å) Mg–Mg bond lengths. There are a spread of Mg–Al bond distances ranging from 3.05–3.16 Å. In the fourth Mg site, Mg is bonded in a 1-coordinate geometry to three equivalent Mg, one Be, and twelve Al atoms.
